Hmm i doubt that to be honest. It all comes down to the keeper and the gecko itself, they will all have differet appetites and growth patterns just like we do so i dont think you can rule out all of them being slow growers. The top photo of my female is one i bought off dragonz and it was a march baby. Like i said before, i got her the same time as reptilez and they were sisters i believe from the same clutch? anyway shes 49grams as of yesterday too so she seems to have a nice growth rate and apetite, not to mention colour so thanks heaps dragonz!
